ED board (PCM-3324S) or ED-2 board (PCM-3348HR)
NORM/E-E (electric-to-normal/electric) switch
This switch controls the signal flow when performing a circuit check.
NORM: Normal operating mode
E-E: Circuit check mode. In this mode, the output of the encoder is input directly to
the decoder, without passing through the head or affecting the tape.
D-OUT NORM/ADV (digital audio signal normal/advance output) switch
ADV OUT (advance output) switches
These switches determine the advance output of the digital audio signal.
The D-OUT NORM/ADV switch is for selecting advance output (ADV) or normal
output (NORM).
Normally all eight individual bit switches of the ADV OUT switches should be in
the left (PCM-3324S) or lower (PCM-3348HR) positions. This represents a value of
255 words, the maximum advance.
Thus, the advance (in words) will be a sum of the values assigned to the switches set
to the left (PCM-3324S) or lower (PCM-3348HR) positions.
The other switches are for factory adjustments only. Do not touch.
MT board
RESET switch
When the level meter display switch is set to HOLD, pressing this switch resets the
peak value being held.
Level meter display switch
This selects how the digital audio channel level meter display operates, as follows:
NORM: Operates as a peak program meter.
2SEC: Operates as peak program meter, but also holds the peak value for
approximately 2 seconds.
HOLD: Operates as a peak program meter, but also holds the peak value when the
RESET switch is pressed.
CAL: Setting for calibrating A/D converter gain
